1-2 STORAGE BEFORE USE
Liberty products are shipped from the factory ready for installation and use. If storage is necessary, the pump should remain in its shipping container. It should be stored in a warehouse or other area that is clean, dry and temperature-stable. The pump and packaging should be covered to protect it from water, dirt and dust.
IMPORTANT: After installation, do not allow the pump to freeze. If the home is allowed to freeze during winter months, ensure the macerating unit and toilet are evacuated of water before closing the home. The tanks should be properly winterized and filled with plumber’s anti-freeze to protect against freezing conditions. The battery should also be disconnected.
2. Introduction
2-1 MACERATING SYSTEM: The macerator is designed to accept wastewater from a rear discharge toilet but can also simultaneously receive wastewater from several sanitary fixtures like a sink, shower, bathtub, or urinal (a single bathroom group). However, only one water closet (toilet) per unit may be connected.
2-2 USAGE: The macerating system is designed for the disposal of human waste, toilet paper and water. It is not intended for kitchen waste, nor is it intended to be used for the disposal of wastewater from such pumped appliances as dishwashers and clothes washers. This product is not designed for emptying large pools or spas.
2-3 TOILET: The toilet works as a conventional flushing toilet and needs no special maintenance in normal use. All standard cleaners can be used just as with a standard conventional toilet.
2-4 BATH LAYOUT: Sanitary fixtures connected to the macerating system must be located on the same floor level.
2-5 AUXILIARY INLETS: The macerator unit is equipped with two inlet ports, one on each side. These ports are designed for standard PVC pipe. Included with the system are two 2” flexible PVC couplers and 1-1/2” reducing bushings. These inlets, which incorporate an internal check valve, are used to connect the drainpipe of other sanitary fixtures to the macerating pump unit. Typically, the 2” drain is used with shower stalls only. A tub, shower/tub combo, or sink would use a 1-1/2” drain line. From the factory, the auxiliary inlets are plugged - if the port is to be used the plug must be removed. The plug can be removed by rotating until the rib is vertical and then pulling outward. If the unit has been stored for some time pliers may be needed to assist in removal.
2” coupler
1-1/2” reducing bushing
2-6 BATHTUBS AND SHOWER STALLS: Any regular bathtub up to 100 gallons or shower can be used. When installing these fixtures, build a 6” high platform on which the fixture is placed. This gives enough space for a p-trap and slope toward the Macerator’s auxiliary inlets. When installing a shower, manufacturers sometimes offer a pre-fabricated raised shower base. NOTE: The actual distance between the p-trap of the additional fixture and Macerator determines the necessary clearance to install the p-trap and elevation required to ensure a minimum pitch of ¼” per foot drop.
2-7 OPERATION: The macerating system starts automatically once the toilet is flushed or liquid from other fixtures enters the unit. It automatically shuts-off once the contents have been pumped away. Run times will vary depending on inflow and source. See Section 2-9 for normal operating cycles.
2-8 USER INTERFACE: The macerator has a user interface (touchpad with LED’s) located on the top left side of the unit. This label contains three LED lights: GREEN – identifies the unit has power, YELLOW – 9-volt battery needs to be replaced, and RED – alarm. If the unit is unable to evacuate the holding tank or cannot keep up with the incoming flow the red light and audible alarm will activate. The label has two push buttons – a “Push to Silence” which will silence the audible alarm and a “Push to Run” which will over-ride the internal switch and manually run the macerator and pump.
©Copyright 2013 Liberty Pumps Inc. All rights reserved. |
3 |
2-9 NORMAL OPERATING CYCLE: The macerator’s IST switch is capable of distinguishing between different modes of operation and optimizes the run time accordingly. Advanced run detection will energize the cutters once the unit detects a flush. In doing so, the cutters are spinning at maximum speed (rpm) prior to fluid and debris reaching the cutting system. The unit may pulse during a shower or draining a bathtub because the macerator can pump at a higher rate than the incoming flow.
2-10 ALARM: The macerator has an integral alarm that will sound if the unit cannot remove liquid or keep up with incoming water. If the alarm sounds, a number of conditions could exist; please see the trouble shooting guide to determine the cause and solution. A silence button located on the user interface touchpad will stop the audible alarm. The alarm light will continue to illuminate. Discontinue using the product until the problem has been identified and resolved. In the event of a power outage, a 9-Volt battery will power the alarm. (Note: In the event of a power outage and if necessary, the macerator will accept two flushes prior to alarm activation. After that, the unit should not be used again until the power is restored.) The alarm automatically resets once a normal cycle is performed. If the yellow light is illuminated on the LED touchpad, the 9 volt battery needs to be replaced. The expected life of the supplied battery is 5 to 7 years.
2-11 ACCESS COVER: The macerator has an access cover that can be removed to gain access to the pumping and macerating cartridge to remove debris or perform maintenance. Once the right hand decorative cover and access cover have been removed, the cartridge can be slid towards the opening to provide access to the basket and cutting mechanism. The blades or entire cutting base can be replaced if needed. See the maintenance section 4-3 of this manual for detailed instructions.
3.Installation
NOTE: All installations should be done in accordance with federal, state and local codes. It is recommended that a certified or qualified installer perform these operations. Do not use an air admittance valve or a mechanical spring-loaded venting device.
3-1 The bathroom layout should be designed prior to installation.
a)Make certain the power source (GFCI receptacle) is within range of the macerator’s 8’ power cord. The cord can be configured to exit the unit on either the left or right side. Do not use an extension cord. When exiting the left side of the macerator the vent flange must be removed so the cord can be routed between the positioning clips. Reinstall vent flange after routing the cord.
b)If possible, the right side of the macerator should remain unobstructed. An access cover is located under the decorative cover that allows access to the cutting mechanism. In the event of a jam, the decorative cover as well as the access cover will need to be removed from the macerator and working room to do so would be beneficial.
c)Auxiliary inlet ports are located on either side towards the back of the macerator’s tank. These ports can accept waste from sink or tub/shower.
d)An optional discharge extension allows the macerator to be positioned behind a wall. For instance, the macerator could be positioned on the floor of a linen closet or utility room. DO NOT fully frame unit into a wall -- access to macerator must be maintained.
e)The macerator features Quickfliptm discharge and vent flanges that can be oriented in a vertical or horizontal orientation to best fit your installation.
f)A sink should be plumbed into one of the auxiliary inlets and not the discharge line of the macerator even if elevations would allow such an installation. The discharge line is pressurized and the plumbing system needs to accommodate this.
g)The water supply line for the toilet tank is located on the left side. When roughing in, pay attention to allow for the macerator.
h)Long downward pitched runs of discharge piping, or piping where the point of discharge is at a lower elevation than the macerator unit, should be designed to prevent siphoning from the macerator tank.
i)Rough in dimensions – The toilet hold down fasteners should be located 16” from the wall and spaced 7” apart. This assumes a typical baseboard of ¾” x 5.5” with ¾” quarter round. Actual baseboard dimensions must be taken into account during the installation and thus rough in dimensions might change.

3-3-3 Assemble the toilet in accordance to the installation manual(s) provided with it. Be careful when tightening fasteners as to not crack the porcelain.
3-3-4 To mount the toilet to a concrete floor, drill two holes approximately 2-1/4” deep with a 5/16” masonry drill bit. Insert plastic plugs into holes. If the floor is wood, bore a pilot hole with a ¼” drill bit.
3-3-5 Place the toilet in front of the macerating tank and apply silicone grease to sealing lip of macerator. Then slide the discharge hub of the toilet into the rubber sealing ring of the macerator.
3-3-6 Place the toilet over the holes in the floor. Slip the plastic china protectors over the lag screws ensure proper orientation. Tighten lag screws (do not over tighten) and snap plastic caps in place.
3-3-7 Connect the water supply line to the fill valve, located directly below the flush lever, on the bottom of the toilet tank.
3-4 CONNECTION TO THE DISCHARGE AND VENT FLANGES
3-4-1 The Macerator has a PVC discharge flange with an integrated check valve that can be configured in a vertical or horizontal orientation. Standard 1” schedule 40 PVC pipe can be solvent welded directly to the flange. Excessive amounts of glue should be avoided. The check valve can be removed from the flange if required. Replacement flanges can be ordered. http://www.libertypumps.com/Service/ReplacementParts/
3-4-2 A “full-port” ball or gate valve and a union should be installed in the discharge pipe to facilitate the removal of the macerator or to perform maintenance if required. In addition, a drain off point is also recommend to allow the discharge piping to be drained if required.
3-4-3 The macerator is equipped with a PVC vent flange, which can be configured in a vertical or horizontal orientation. Standard 1-1/2” Schedule 40 PVC pipe can be solvent welded directly into the flange.
3-4-4 The macerator must be vented to allow for proper toilet flush performance. Depending on the installation, the product should either be connected to the stack vent of the dwelling or vented (plumbed) directly outside.
3-4-5 ***Do not use an air admittance valve or a mechanical spring-loaded venting device, as these devices are one-way valves. The air pressure in and outside the macerating pump unit must be equal, a “cheater” vent will obstruct the airflow in one direction and prevent proper toilet function.
3-4-6 The Macerator is not designed to support the discharge and vent piping; proper pipe hangers are required.
3-5 CONNECTION TO THE SOIL-STACK OR SEWER
3-5-1 The macerator has a shut-off head of 36 feet. All frictional losses from horizontal runs and elbows need to be accounted for. The minimum flow rate for 1” PVC sch. 40 pipe is 5 gal/min compared to 3 gal/min for ¾” PVC pipe. If you require a vertical lift, it should precede any “horizontal” run and should commence as near as possible to the discharge of the macerator. Once you have started the horizontal run, you may not change directions in a vertical manner.
NOTE: Friction losses from horizontal runs without ¼” per foot pitch will reduce the amount of vertical lift the system is capable of handling. See sections 3-5-2 and 3-5-3. Consult factory for proper sizing if you have long runs or multiple elbows. Phone: 1-800-543-2550.
3-5-2 The discharge piping can be made from ¾” or 1” diameter CPVC or PVC pipe. Use long turn bends and not elbows where possible. The connection to the soil-stack or sewer pipe should be made with an approved wye fitting.

3-5-3 If you wish the unit to pump vertically and horizontally you may calculate 3 feet of vertical lift is equivalent to 30 feet of “horizontal” run. Each bend or change of direction gives a pressure drop, which must be calculated into the total head of the unit. As an estimate, reduce discharge height by 3 feet for each 90° bend.
For example: 1” SCH. 40 PVC pipe is used for the discharge and runs horizontally for 1’; then turns 90° and rises 5’ vertical. Then it travels horizontal with another 90° turn (3 turns in total) and connects with the soil-stack. See illustration below.
Calculations:
Total vertical lift 5’ 5’ vertical
Total Horizontal run 43’ 4.3’ vertical Total of three 90° elbows 9’ vertical
Now add the three together we get 18.3’ of vertical lift. Reading the performance curve below indicates the application would result in a flow rate of 23 gal/min(60Hz).
All fixtures must be properly vented
Tub / Shower should be installed
on a riser to accommodate the P trap

3-6 CONNECTION TO ELECTRICAL SUPPLY
3-6-1 All wiring should be done in accordance with the applicable electrical codes. The macerating system requires a properly sized single-phase GFCI (ground fault circuit interrupter) type receptacle. Receptacle should be installed in accordance with local and state electrical codes. It is recommended that the receptacle be 40 inches away (in a straight line) from a shower or bathtub. If installation is performed in a basement, the receptacle should be 48 inches from the floor.
3-6-2 If the electrical power receptacle (outlet) is in close proximity to the macerator, the “extra power cord” can be coiled and tucked away in a large depression designed into the access cover that is located under the right decorative cover.
Risk of electric shock. This pump is supplied with a grounding-type attachment plug. To reduce the risk of electric shock, be certain that it is connected to a properly grounded, grounding-type receptacle.
3-7 EXTENSION PIPE
3-7-1 To install the macerator behind a wall, a Liberty extension pipe kit # K001184 (sold sperately) will be needed. Included in the kit are an 18.75” long extension pipe, a decorative trim ring, and a grease packet. Rubber rings seal both ends of the extension pipe. To prevent tearing, always grease both seals prior to installing the pipe. Slip the decorative trim ring onto the pipe. To install the pipe, no fasteners are required, slip the extension pipe over the toilet’s discharge, and then insert the pipe into the macerator. To finish the installation, fasten the toilet to the floor and secure the macerator discharge and vent piping. For proper flushing performance, ensure that the base of the toilet is not below the base of the macerator. Check the extension pipe with a level, and verify that the pipe is either level or sloped towards the macerator unit and away from the toilet.
3-7-2 Liberty recommends only one extension pipe be used.
3-8 INSTALLATION TIPS
3-8-1 PIPE SUPPORTS: All sanitary pipe work must be supported in accordance with the pipe manufacturer’s recommendations. Avoid dipping or trapping, which may cause the buildup of residual “solids” and subsequent blockage.
3-8-2 BENDS: Wherever possible, long sweeping bends should be used. Do not use short elbows. If sweeping 90° elbows are not available, use two 45° elbows to make a 90° turn.
3-8-3 VERTICAL PIPING FIRST: If vertical lift is required, this must precede the horizontal pipe run.
3-8-4 BATTERY: Battery must be installed AFTER the macerator is connected to the AC power supply. Failure to follow this procedure could result in the unit not functioning properly.
3-8-5 DIRECTLY VERTICAL: All vertical lifts should rise as close to the macerator
as possible, allowing only for the need to clear the toilet tank; the initial horizontal run should not exceed 12”.
3-8-6 NO DIAGONAL “UPHILL” PIPE RUNS: All discharge piping from the unit should run either directly vertical or in a horizontal plane (with a minimum ¼” per foot drop) to the point of discharge. Pipe work must not be installed with a diagonal upward slope from the unit to the point of discharge.
3-8-7 EASY ACCESS: The unit should be accessible and removable in the event of maintenance being required. During the installation, a full-port ball valve should be installed near the discharge flange to allow easy service of the unit.
3-8-8 GRAVITY FALL: The unit accepts wastewater by gravity; it does not “vacuum” in water. All inlet pipe work must have a positive gravity fall (1/4” per foot drop minimum). All horizontal piping from the macerator must also have a ¼” per foot drop to allow free drainage when the pump stops.
3-8-9 SOIL STACK CONNECTION: All discharge pipe work must be connected to the soil stack by an appropriate and approved connection like a “tee” or “y” fitting.
3-8-10 PIPE WORK: All pipe work should be copper, PVC, or CPVC. Do not use flexible piping. Hangers should not be less than 4 feet apart to prevent pipe rattling.
3-8-11 FLUSHING: Macerator is designed to work with a low flow toilet (1.28 gallons per flush).
3-8-12 DISCHARGE: Never discharge directly into an open drain, fixture, manhole or rainwater drainpipe. It is illegal, as it constitutes a health hazard. Direct connections into sanitary waste systems only shall be acceptable.
3-8-13 FREEZING: Ensure all pipe work susceptible to freezing is adequately insulated or heated. In unheated buildings, the toilet, piping and macerating unit must be properly winterized. Use plumbers’ anti-freeze or drain completely.
3-8-14 ELECTRICITY: The macerating system must be connected to a Ground Fault Circuit Interrupter (GFCI). Before attempting any maintenance or servicing, the unit must be disconnected from the power source.
3-8-15 SHOWER: The water height will be 4.5” in the Macerator tank before the unit starts pumping. The shower stall floor must be well above this level, Liberty recommends at least 6” - 8” to ensure proper shower drainage and prevent any backflow.

4-1 |
ACTIVATING THE UNIT |
|
|
4-1-1 |
Ensure that the toilet / tank have been assembled per the instructions provided with the toilet tank. |
|
4-1-2 |
Ensure any ball or gate valve in the discharge line is in the open (full flow) position. |
|
4-1-3 |
Open the shut-off valve and let the toilet tank fill up. Look for leaks at connections. |
|
4-1-4 |
Ensure the macerating unit has both decorative covers installed and is plugged in with the power supply turned on. |
|
|
The green light should be illuminated. If the green light is blinking, check to confirm the decorative covers are |
|
|
properly seated. |
|
4-1-5 |
Deposit a few sheets of toilet paper into the bowl and flush the toilet. There should be no paper remaining in the bowl |
|
|
after the flush. This should be repeated several times. |
|
4-1-6 |
Either flushing the toilet or the height of water in the tank activates the Macerator’s adaptive switch system. The unit |
|
|
will turn on shortly after the toilet is flushed or when a water depth of 4.5” is achieved. The duration of operation will |
|
|
differ depending upon the installation. Note, the Macerator may not run immediately upon sink usage. |
4-2 |
CAUTIONARY NOTES |
|
|
4-2-1 |
The macerating system is designed for human waste and toilet paper. |
|
4-2-2 |
Do not dispose of acids, alkalis, solvents, oils, paint, paint strippers, food waste, and cotton swabs. Off-the-shelf toilet |
|
|
cleansers will normally not hurt the macerating unit. During cleaning or when using a plunger the macerator could |
|
|
turn on. |
|
4-2-3 |
Do not hang bleach blocks or hypochlorite cleaners in the toilet tank. These solutions have been shown to |
|
|
deteriorate the plastic and neoprene components of the flush and fill valves, and may cause leaks. |
|
4-2-4 |
In the event of a power loss, the toilet can be used twice. Use of sanitary fixtures like a sink should be limited. Do not |
|
|
use shower or tub as the macerating unit will fail to pump until the power is restored. |
4-3 |
MAINTENANCE |
|
|
The macerator is designed such that every component can easily be serviced or replaced if required. |
|
|
|
Risk of electric shock, always disconnect the macerator from the power source before handling or making |
|
|
adjustments. Health hazard: sharp blades within unit, wear rubber gloves. |
|
4-3-1 |
Decorative covers: Both the right and left decorative covers sit on the product and are retained with some simple clips |
|
|
and posts. The right side can be removed by pulling it horizontally away from the macerator and then lifting vertically. The |
|
|
left decorative cover is secured and positioned by two mating posts on the main cover. |

4-3-3 Check Valve: The discharge flange has an integrated check valve. The valve is held in place by a support backing plate that is also connected to the discharge hose. To access the check valve, first remove the discharge flange from the main cover by removing 4 screws. Then, remove the hose followed by the two screws. The hose nipple can then be separated from the flange by pulling it outward. The check valve snaps onto the hose nipple. When reinstalling, the hinge of the check valve must be aligned with the “notch” in the hose nipple or backing plate. After installation of the hose nipple, confirm the check valve opens completely.
4-3-4 Access cover: The access cover is secured to the main cover with five fasteners. If required, use the 3/16 Allen wrench supplied to loosen the fasteners. Once the screws have been removed, the access cover can be lifted upward. Some manipulation might be necessary if the Macerator is located directly under the toilet’s reservoir tank.
Once the access cover is removed pull the power cartridge towards opening
a)Once the access cover is removed, the power cartridge can be slid towards the opening by grasping the handle of the basket and pulling to the right towards the opening. In some instances, debris might be caught between the tank and the basket so some manipulation might be required.
b)With the power cartridge fully slid over, the cutters should be in view at the center of the basket. Any obstruction or object can be removed at this point. The cutters are very sharp and extreme caution should be used.
c)To replace the cutters the 3/16 Allen wrench (supplied) should be inserted into one of the holes located on the basket floor. This will create a wedge preventing the blade assembly from turning. The locking fastener can be unscrewed with the use of a 7/16” socket (1/4” drive). Once loose, the screw and cap can be removed by pulling upward which exposes the two razor blades. Liberty Pumps recommends stainless steel blades, although any common utility knife style razor blade with two holes can be used as a replacement. When replacing the razor blades simply insert the blade onto the two pins. The cap and screw should then be replaced.
d)The base of the cutting cartridge can be replaced as well. After removing the razor blades a thin slotted screwdriver can be inserted into the center hole and once engaged the base can be rotated counterclockwise until it is free.

4-3-5 Accessibility to Motorized cartridge:
The motorized cartridge can be accessed through the access opening or removal of the main cover.
1)Removal of power cartridge through the access opening:
Once the access cover has been removed and the basket is slid towards the opening, the four fasteners securing the basket can be unscrewed. The basket can then be removed through the opening followed by the power cartridge.
2)Removal of power cartridge by disassembly of macerator:
If a ball valve was installed in the discharge line, it should be closed to eliminate the possibility of waste discharging from the discharge pipe. Next, the discharge and vent flanges should be separated from the main cover by removing 4 screws from each. The main cover can then be detached from the tank by removing the fasteners on the periphery of the tank. The main cover can then be lifted upward exposing the power cartridge.

11 |
The inner connecting power cord running from the switch box to the motorized cartridge can be detached by unscrewing the compression nut located at the motorized cartridge.
4-3-6 Removal of blockage from impeller / impeller replacement:
Once the bottom of the motorized cartridge is accessible, the fasteners retaining the volute can be removed and the volute separated by pulling it away. The impeller chamber can now be cleaned if required, or the impeller can be replaced. NOTE: the impeller has a left-handed thread. To remove, use a slotted screwdriver to hold the shaft and turn the impeller clockwise.
4-3-7 Interconnect hose:
A hose connects the discharge of the motor cartridge (pump) to the discharge flange. To remove this hose, follow the procedure to remove the discharge flange and motorized cartridge. Both ends of the hose are secured with clamps.
4-3-8 Control Switch:
The control switch cartridge is mounted to the main cover with fasteners. The control has two power cords, first is the main power cord that plugs into the house receptacle and the other powers the motorized cartridge. The motorized cartridge must be removed to

disconnect this cord. See instructions under the heading “Accessibility to Motorized cartridge 4-3-5” for details.
4-3-9 Toilet sealing ring:
The seal between the toilet and the macerator consists of a rubber ring connected to the macerator to which the toilet slides into. The rubber ring stretches and forms a seal around the discharge hub of the toilet. This rubber ring is replaceable by unclipping the plastic retainer and then pulling the ring outward. Installation is reverse, first slide the rubber ring onto the macerator followed by the retaining ring.
5. Troubleshooting
5-1 BEFORE REFERRING TO TROUBLESHOOTING CHART
5-1-1 Check plumbing system. Flush toilet and ensure water supply is turned on.
5-1-2 Check electrical system. Ensure breaker and receptacle GFCI are on. Check condition of circuit breaker or fuse. Ensure plug is not loose. If the pumping unit’s thermal overload has activated, it will take about 20 minutes to reactivate.
5-1-3 Ensure decorative covers are installed and fully seated such that safety switch is activated. The green light should be solid green if safety switch is properly activated.
5-1-4 Check the hydraulic system. Check that the discharge pipe and vent pipe are not blocked.
5-1-5 If the macerating pump turns on intermittently without flushing the toilet or collecting water drainage from sink, shower, or tub, check for leakage from the toilet tank flush valve.
